The Revell '29 pickup is the finest Model A pickup that can be bought in 1/25 scale.
Unfortunately, a proper '30-'31 cab pickup has not been done in 1/25.
It's out again under in the "Car Show" series in a Monogram box:
It has a delicate suspension system because it is ACCURATE and true to scale.
You must remember that Model A pickups were manufactured on the passenger car chassis.
Only Model AA trucks (1-1/2 ton and 2-1/2 ton) were any beefier than the passenger cars, and they had totally different frames, suspensions, wheels, tires, axles, brakes, and transmissions. The engine, cab, hood, radiator (but not radiator shell), headlamps, headlight bar, and front fenders were the only components common/interchangeable between the Model A passenger cars/pickups and the Model AA trucks.
